RKI Instruments Eagle Portable Monitor for LEL Methane (IR)/O2 - 72-5201RK-IR


72-5201RK-IR Eagle Portable Monitor for LEL Methane (IR)/O2 by RKI Instruments

The Eagle Portable Monitor can simultaneously detect up to 6 different gases. With over 400 gas monitoring configurations, the unit can detect a wide range of toxic gases. RKI Industries offers long life protection for workplace safety and hazardous jobsites. With a reputation for advanced engineering and state of the art technology, the RKI Industries' Eagle One to Six Gas Portable Monitor is an industry leader in accuracy and affordability.


The Eagle One to Six Gas Portable Monitor is available with a wide variety of exclusive features. The unit is capable of PPM/LEL hydrocarbon detection and for environmental use, has a methane elimination switch. The dual hydrophobic filters (available on some models) ensure quality control. To preserve the integrity and safety of the device, the portable monitor also has an adjustment lockout switch to prevent tampering. For quick and easy testing, the monitor offers autocalibration and single gas calibration.

The Eagle is housed in an ergonomic RFI, EMI, chemical, and weather resistant polycarbonate and polyester enclosure. It can operate in the rain or in 2 inches of water without damage. It features an ergonomically designed top handle to ensure durability.

Accessories and Options

IR Sensors are available for CO2, % LEL CH4 or HC, and % volume CH4 or HC. Each unit also has datalogging capabilities for research, evaluation, and analysis of worksite atmospheres. The unit comes standard with several accessories including a shoulder strap, alkaline batteries, a hydrophobic probe, a 5 foot hose, and an internal hydrophobic filter with most models. Optional accessories can be purchased to fully customize the portable monitor to meet specific needs including a datalogging kit, remote alarms, dilution fitting, Ni-Cad batteries, battery chargers, continuous operation adapter, extra loud buzzer, extension probes, and large internal hydrophobic filter.


The Eagle has a battery life of up to 30 hours of continuous operation with alkaline or Ni-cad capability and a sensor life of approximately 2 years. Its standard weight is approximately 5 pounds with dimensions of 10.5L x 5.9W x 7H. The formidable long life pump (with a life of approximately 6,000 hours) reaches up to 125 feet in range with filters and has a low flow pump shut off and alarm. The unit has a response time of up to 30 seconds for most gases, and features a double alarm of audible alerts at 85 dB and visual alerts of dual high intensity LEDs and a flashing display screen.

The display screen is an easy to read 4 x 20 LCD readout. The backlit display sits at the top of the unit for full visibility, and displays the readings and statuses of 4 channels simultaneously.

The portable monitor is rated as intrinsically safe and has a standard 2 year warranty for materials and craftsmanship.
